A monitoring device for a pipe system includes a housing, a housing fastener, and a strap assembly. The housing is configured to mount on an exterior surface of a pipe element of the pipe system. The strap assembly is coupled to the housing with the housing fastener, and the housing fastener is received within the housing to secure the strap assembly to the housing. The strap assembly includes a first strap and a second strap, each of the first strap and the second strap including a mounting end, an adjusting end, and an intermediate portion. The first strap includes an insert tab proximate to the first adjusting end, and the second strap includes a plurality of adjustment slots sized to lockably receive a portion of the insert tab. The insert tab is lockably coupled to the second strap when the monitoring device is tightened.

A pipe joint structure has a joint body, a fixed ring and a union nut. A flared end of a tube has a conical surface and a tubular surface. The conical surface and tubular surface are connected to a tube connecting portion of the joint body. The union nut is fastened to a locking thread of the tube connecting portion. An interior recess portion of the union nut is coupled with a bulging surface of the fixed ring. The tube is compressed evenly and secured firmly on the joint body.

A tubing system includes a fluid carrying tubing; a first jacket encasing the tubing; a second jacket encasing the first jacket; the second jacket including a plurality of longitudinally extending ribs circumferentially arranged on an inside surface of the second jacket.

A sea hose load analyzer system is disclosed. The sea hose load analyzer system also includes a transceiver interface. The sea hose load analyzer system also includes a memory storage. The sea hose load analyzer system also includes circuitry may include one or more processors configured to: receive load information of one or more sea hoses as node unit data via the transceiver interface, store the load information in the memory storage, and monitor additional node unit data via the transceiver interface.

An integrity monitoring system for a lined pipeline is provided for monitoring the integrity of a polymer liner in a host pipe. Methods and apparatus are described by which a lined pipeline is provided with such an integrity monitoring system. Sensor cable is able to bridge a joint between sections at lined pipe, for example by routing the sensor cable across the joint via a channel in an electrofusion fitting or by connecting successive lengths of sensor cable via pass-throughs in an electrofusion fitting. Advantageously, the sensor cable is disposed within a continuous annulus between linings and host pipes, and the continuous annulus is maintained across pipe joints using electrofusion fittings.

A seal apparatus provides sufficient sealing and is compact and inexpensive. The seal apparatus includes a thread part screwed to the screw fastening part of a hollow component; a seal part that moves along an axis of the screw part and comes into pressure contact with the screw fastening part of the hollow component; a stopper part fixed to the screw part that restricts the movement of the seal part; a pressed part that moves the seal part into pressure contact with the screw fastening part; a spring disposed between the pressed part and the stopper part; and an accumulator formed between the stopper part and the seal part and into which a test fluid which is introduced into the hollow component for inspection flows.

A petroleum pipeline safety system for preventing contamination of an environmentally sensitive area close to a pipeline includes an upstream portion of the pipeline supplying a flow of fluid material, a crossing portion of the pipeline receiving the flow of fluid material from the upstream portion and conveying the flow of fluid material through the environmentally sensitive area to a downstream portion of the pipeline, the downstream portion, a pipeline pressure activated valve selectively capable of blocking the flow of fluid material from entering the crossing portion based upon a change in pressure within the crossing portion, and a fluid capacitor connected to the upstream portion configured to filter out a pressure spike in the upstream portion associated with the valve blocking the flow of fluid material.

A low point raceway fitting for draining accumulated condensation from electrical raceway systems installed in industrial, commercial and residential facilities. The drain fitting is a tubular member having a throughbore for pulling wire, connecting ends for installation in a raceway system, and an enlarged section between the ends profiled for engagement by a tool for installation. A drain passage is formed radially through the tool engaging section and is positioned at the underside of the horizontal fitting for gravity drainage. A screen insert can be placed in the drain passage to keep dirt and insects out.

To provide a fuel pipe of an aircraft that makes it possible to maintain temperature of fuel in the fuel pipe at appropriate temperature while giving consideration to reliability that is constantly required for the aircraft. A fuel pipe provided in an airframe of the aircraft includes: an inner pipe defining a flow path through which fuel flows; and an outer pipe surrounding an outer periphery of the inner pipe. A gap is provided between the outer periphery of the inner pipe and an inner periphery of the outer pipe. The inner pipe is made of a rubber material, and the outer pipe is made of a metal material.

Device for a double hose structure with an inner main hose and an outer cover hose defining an annular space giving buoyancy in water. At least one end is provided with a coupling member forming a mount for the main hose and the cover hose which at a free end merges into a threaded portion for connecting the hose assembly to an auxiliary connection. The coupling member comprises an inner coupling sleeve connected to one end of the main hose and an outer coupling sleeve connected to the cover hose, the inner and outer coupling sleeves being mutually connected forming a liquid tight termination of the annulus by a ring-shaped plate. The plate is attached with screws through holes only to the outer sleeve, the plate being forced against a shoulder of the inner coupling sleeve by a ring nut with internal threads matching external threads on the inner sleeve.
